Lifejacket Service

For 5 years, no major service of the Hammar inflator cap is required – but all inflatable lifejackets requires:

  • an annual inspection to ensure functionality. Annual inflatable life jacket service by an authorised service station, is a requirement for SOLAS approved lifejackets for professional use, but also a strong recommendation from authorities worldwide for recreational users.
  • In order to maintain top performance, make sure to also follow the instructions for periodic service of your life jacket.
Check periodically

  1. The single point indicator on the inflator cap is green. ( )
  2. The expiry date on the inflator cap is within limit.
  3. Always inspect the sealing ring for wear and tear that can affect the sealing function, and pull the cap and locking ring to make sure it has locked on the inflator body properly.
  4. Inflate the MA1 lifejacket through the oral tube and check that it stays inflated at least over night.





Packing
Before packing, deflate the lifejacket through the oral tube and make sure that all residual air is pressed out from the bladder so that it can be folded properly according to the manufacturer’s instruction. Make sure that the lifejacket is dry before packing.

This is how to rearm a MA1 life jacket:

Before you start rearming, make sure you have a smooth, flat and dry work surface.

  1. Insert the opening key between the black locking ring and the yellow cap and turn the key counter clock-wise. The black locking ring will now turn counter clock-wise.
  2. Hold the yellow cap with one hand and continue to turn the black locking ring counter clock-wise with the other hand until it stops.
  3. Lift off the yellow cap. Remove the old inflator body and gas cylinder from inside the bladder and dispose it in an environmentally friendly manner.
  4. Check the Hammar MA1 rearming kit. Ensure that all four points are met before you continue.
    • On the inflator cap: color of the single point indicator is green. ( )
    • On the black body: the indicator is green. ( )
    • The inflator caps expiry date: is within limit.
    • The size of the gas cylinder is correct.
      Do not assemble any cap or body that does not meet these requirements.
  5. Insert the inflator body with the gas cylinder pointing upwards in the bladder. Let the sealing ring rest on the rounded sealing surface on the body.
  6. Position the replacement cap with the hydrostatic valve pointing to the right, 90° relative the gas cylinder and put the cap in place at the body.
  7. Press firmly on the inflator cap and turn the black locking ring clockwise into the locked position.

FINAL CHECK

  • To make sure the cap has locked on the MA1 inflator body properly: pull the cap.
  • Check that the locking ring cannot be turned counter clockwise by hand: if it cannot be turned, it is properly locked.
  • Check that the inflation is working properly, by inflating the lifejacket through the oral tube. Check that it stays inflated at least over the night.

Packing
Before packing, deflate the lifejacket through the oral tube and make sure that all residual air is pressed out from the bladder so that it can be folded properly according to the manufacturer’s instruction. Make sure that the lifejacket is dry before packing.

This is how to rearm a A1/M1 life jacket

Before you start rearming your lifejacket, be sure to have a flat, smooth and dry work surface.

  1. Use the opening key, and insert it between the black locking ring and the yellow cap. Then turn the key counter clock-wise. Now, the black locking ring will turn counter clock-wise.
  2. Continue to turn the black locking ring counter clock-wise until it stops: hold the yellow cap with one hand and the black locking ring with the other hand.
  3. You can now lift off the yellow cap. From inside the bladder: remove the used gas cylinder. Be sure to then dispose it in an environmentally friendly manner.
  4. Reset the piercing pin by rotating the shaft in the inner body to a position where the underside monitor with eyelet surrounds the green dot ( ) in the centre of the indicator.
  5. Carefully examine the top of the new gas cylinder to make sure that it is not punctured. The cylinder must be very firmly tightened into the black inner body. The black inner body should be checked for any damage or splitting following this tightening.
  6. Check your Hammar A1/M1 rearming kit. Ensure that all conditions are met before you continue.

    • Make sure that the red handle is attached.

    If YES is the answer to ALL these questions, then proceed to:

  7. When you insert the inflator body: make sure that the gas cylinder is pointing upwards inside the bladder. The sealing ring can rest on the bodys rounded sealing surface.
  8. Make sure that the position of the hydrostatic valve in the replacement cap is pointing to the right, 90° relative the gas cylinder. Put the replacement cap in place at the body.
  9. First: press firmly on the inflator cap, and then turn the black locking ring clockwise until the locked position is reached.

FINAL CHECK

  • Make sure the cap has been locked on the inflator body properly: by pulling the cap.
  • The locking ring should not be able to be turned counter clockwise by hand. Try to turn the locking ring, to make sure it is properly locked.
  • Inflate the Hammar A1/M1 lifejacket through the oral tube, to make sure it can inflate properly. Check that it stays inflated at least over one night.
  1. Make sure that the red handle is attached.
  2. Check that the gas cylinder is firmly tightened. Do this by simply holding the gas cylinder through the lifejacket fabric.
  3. Make sure you always inspect the sealing ring for wear and tear that can affect the sealing function.
  4. Inflate the lifejacket manually through the oral tube, and check that it stays inflated over one night.
